Problems solved by technology

This assembly mode is very time-consuming and labor-intensive.
[0008] Next, since the hook body of the hook is embedded in the circular groove of the blade, there is no possibility of compression deformation, and there is a problem of limited use

Embodiment 1

[0039] Such as figure 2 , image 3 , Figure 4 and Figure 5 As shown, pins are set on the first blade set 1 . In this example, the pins include a first pin 41 and a second pin 42 that can adopt the same size and shape. In this example, the first pin 41 and the second pin 42 can be cylindrical. Of course, This is only an example, and is not intended to limit the present invention. In this example, other shapes such as cylinders can also be used. In addition, the first pin 41 and the second pin 42 can be the same size and shape, or they can be different. However, it is relatively convenient to install the first pin 41 and the second pin 42 with the same size and shape. The first pin 41 and the second pin 42 are detachably connected to the first blade set 1 , and the second blade set 2 and the third blade set 3 are respectively provided with annular grooves adapted to the pins. For example, the two blades of the first blade set 1 are provided with a first annular groove 11...

Embodiment 2

[0046] A cutter shaft strengthening mechanism for a paper shredder, comprising two parallel cutter shafts and blade sets respectively fixed on the two cutter shafts and interlaced with each other, each blade set includes two blades, wherein the adjacent blade sets A reinforcing mechanism is provided on the blade, and the reinforcing mechanism includes a reinforcing body and an accommodating body respectively arranged on the blades of the adjacent blade groups and adapted to each other, and the reinforcing body is detachably arranged on the blade group superior. In this embodiment, two groups of strengthening mechanisms are provided, and the two groups of strengthening mechanisms are separated by one blade group, and are all arranged in the middle of the cutter shaft. During specific implementation, the number and positions of the reinforcing mechanisms can also be changed, which are not limited here. The following will take one group of reinforcement mechanisms as an example ...

Abstract

The invention discloses a paper shredder cutter shaft strengthening mechanism. The mechanism comprises two cutter shafts arranged in parallel, and staggered blade sets respectively fixed on the two cutter shafts. Each blade set comprises two blades. A strengthening mechanism is arranged on blades of adjacent blade sets. The strengthening mechanism comprises mutually adapted reinforcing body and accommodating body respectively arranged on the blades of the adjacent blade sets. The strengthening mechanism is detachably arranged on the blade sets. With the mechanism provided by the invention, when plural pieces of papers are shredded simultaneously, the cutter shafts are prevented from being spread. The strengthening mechanism has the advantages of simple structure, convenient processing and manufacturing, and easy assembly.

Description

technical field [0001] The invention relates to the field of paper shredders, in particular to a strengthening mechanism for a cutter shaft of a paper shredder. Background technique [0002] The shredding mechanism of a paper shredder usually consists of two cutter shafts arranged parallel to each other and a blade group arranged on the cutter shaft. Each blade group is composed of two blades, and the blade groups are separated by a knife ring. The blade sets on the two axes are staggered to form an intersecting area. The paper enters between the two cutter shafts from the intersecting area, and is crushed by the relatively rotating blade group. [0003] Due to the long span of the cutter shafts, when the paper enters the intersecting area, the cutter shafts are inevitably deformed, that is, the two cutter shafts are deformed respectively to increase the distance between them to accommodate the paper. However, if the paper entering the shredder is too thick, the intersecti...
